With my argument on "Should men and women accept their lover to watch the adult video or not?", I found some sources to prove my opposition.
I found a website made by a famous brain scientist 洪蘭 in Taiwan. And in the website she introduced her book which discussed about brain's every reaction. According to one of paragraph in this book, it talked about "people's addiction".
It mentioned that through some experiments, our brain's plasticity was related to dopamine(多巴胺). When our nerve received the instruction from cerebrum and then complete it, dopamine could let the nerve get more stable. Easy to say, the more dopamine, the connection of nerve would get more tight, this is the reason why we have addition. And once this kind of energy accumulate too much on nerve, it will cause an irreversible change, that means even people get rid of addiction eventually, brain will still memorize this influence.
So my opinion is "sexual addiction" is without exception as well, I think people was addicted to watch adult video probably.
Another point connect in above-mentioned paragraph, it said "Some people say that adult video provide people a healthy pleasure, can liberated from the sexual tension, however adult video is addictive, and provide resistance, actually it may reduce the feeling of happiness. People who addicted to adult video will long for adult video but don't like it; people who continued to watch adult video will think their lover were unattractive, and would rather watch adult video than dating with real person." It means that adult video may let people cannot tell reality from fantasy.
Further, in fact this issue is a trouble to the girls mostly. Because of this worry, they will try to ask some advise on the Internet after their lover did not consider their annoyance as a problem.(source2) Then usually they will get some users' responses that told them to understand their lover, even told them"Rather let your boyfriend watch adult video without make an extramarital affair." These kind of opinion usually make girls compromise. Someone may also said that watching adult video was just for physiological needs. But why especially someone already had a beloved still need to rely on watching adult video? There is another news about this issue.(source3)
Even if watching adult video won't be addiction to everyone, does this behavior won't let people fall into the fictitious and porn world? After all adult videos are still commodities, a commercial practices, include many unrealistic and exaggerating content to fascinate viewer. So I convinced that watching adult videos could generate some over illusion. Therefore, this topic is not only against on "man" watch adult video, is about your "lover" who need to watch adult video as before would might cause influence between your relationship.
